The polymer blends of Polymethyl Methacrylate/Polystyrene (PS/PMMA) ha
ve been irradiated with Si-28 ions of 60 MeV. The percentage transmiss
ion of light in the wavelength region of 490 nm has been studied with
varying concentration of PS in blend films before and after irradiatio
n. The transmission of light increased on irradiation which may be att
ributed to the chain scissions of PMMA. (C) 1998 Elsevier Science Ltd.
